Correlates of subjective health in older adults: a meta-analysis.

Age-associated changes of subjective health and associations of subjective health with physical health, functional health, and mental health were meta-analyzed in older adults (M age > 60 years). An age-associated decline of subjective health, which was stronger in old-old samples than in young-old samples, was found. Subjective health was correlated with the indicators of objective health, but the association with physical health was stronger than with functional health. Correlations of subjective health with physical health and functional health were lower in the old-old than in the young-old samples, whereas associations of subjective health with mental health were stronger in older samples. Furthermore, the size of the association between subjective and objective health varied by the method of assessment of objective health, showing highest associations with symptom checklists and results of medical examinations due to strict protocols.
